The watershed summit in 2015 was far from perfect, but its impact so far has been significant and measurable

Ten years on from the historic Paris climate summit, which ended with the world’s first and only global agreement to curb greenhouse gas emissions, it is easy to dwell on its failures. But the successes go less remarked.

Renewable energy smashed records last year, growing by 15% and accounting for more than 90% of all new power generation capacity. Investment in clean energy topped $2tn, outstripping that into fossil fuels by two to one.

Scientists in Kansas believe Kernza could cut emissions, restore degraded soils and reshape the future of agriculture

On the concrete floor of a greenhouse in rural Kansas stands a neat grid of 100 plastic plant pots, each holding a straggly crown of strappy, grass-like leaves. These plants are perennials – they keep growing, year after year. That single characteristic separates them from soya beans, wheat, maize, rice and every other major grain crop, all of which are annuals: plants that live and die within a single growing season.

“These plants are the winners, the ones that get to pass their genes on [to future generations],” says Lee DeHaan of the Land Institute, an agricultural non-profit based in Salina, Kansas. If DeHaan’s breeding programme maintains its current progress, the descendant of these young perennial crop plants could one day usher in a wholesale revolution in agriculture.

Guardian story helped to draw attention to planned hanging of Goli Kouhkan over death of abusive husband

A child bride who was due to be executed this month in Iran over the death of her husband has had her life spared by his parents, who were paid the equivalent of £70,000 in exchange for their forgiveness.

Goli Kouhkan, 25, has been on death row in Gorgan central prison in northern Iran for the past seven years. At the age of 18 she was arrested over allegedly participating in the killing of her abusive husband, Alireza Abil, in May 2018, and sentenced to qisas – retribution-in-kind.

After record flooding submerged Bor in South Sudan in 2020, the emergency response ended up turning it into a beacon of climate crisis adaptation

The three friends fill yellow jerrycans and help each other lift them on to their heads for the short walk home. Nyandong Chang lives five minutes from the water kiosk and is here up to six times a day. “It’s still hard work,” she says, “but at least nowadays water is available and clean.”

Until last year, women and children in Bor, the capital of South Sudan’s Jonglei state, faced a much tougher chore – going all the way to the filthy stretch of the White Nile that runs near the town to draw the family’s drinking, washing and cooking water and carry it back.

Women work longer and per hour earn a third of what men are paid, in figures that have changed little in 35 years, UN report shows

“Gender inequality is one of the most entrenched and significant problems of our time,” says Jocelyn Chu, a programme director at UN Women, responding to the stark figures contained in this year’s World Inequality report, which labels gender inequality a “defining and persistent feature of the global economy”.

Women work longer and earn just a third – 32% – of what men get per hour, when paid and unpaid labour, such as domestic work, are taken into account. Even when unpaid domestic labour is not included, women only earn 61% of what men make, according to the report.

Despite the challenges of working in a healthcare system in crisis, Kudzai Kanyepi has resisted the temptation to move abroad

When Dr Kudzai Kanyepi qualified as Zimbabwe’s first female cardiothoracic surgeon four years ago, she was filled with pride and anticipation after succeeding in an area long dominated by men. She was only the 12th woman in Africa to qualify in the field – four more have joined her since.

Even now, with 100 operations under her belt, the reality of working in a role in which she confronts misogyny and discrimination daily has not dented Kanyepi’s love of the surgical theatre.

Exclusive: Guardian investigation finds fake agencies using the social media platform to dupe Kenyans into paying for nonexistent jobs in Europe

Lilian, a 35-year-old Kenyan living in Qatar, was scrolling on TikTok in April when she saw posts from a recruitment agency offering jobs overseas. The Kenya-based WorldPath House of Travel, with more than 20,000 followers on the social media platform, promised hassle-free work visas for jobs across Europe.

“They were showing work permits they’d received, envelopes, like: ‘We have Europe visas already,’” Lilian recalls.
